HTall @cham it majconcern:

Bel itzknown that we, MAURICE A. Bmmr i' States, residing at Croghan, in the countyof 5 Lewis and State of New York, have invent- '1 `ed certain new and usefulImprovements in Ice-CuttingA paratus, of which the following is a speci catiom This invention relates to new and useful 1o improvements in Vice cutting apparatus and l `consists essentially in the provision of a sled fcarl'ying `an adjustable saw drivenv by' an)7 suitable power mechanism and in the; pro-f' vision vof means for'holding the saw in diffbficientapparatus ofthissnature, aving various details of construction, combinations L and arrangements i of parts whichs/will vbe La ifzohereinafter fullyfdescribed,`shown in the accompanying drawings and then specifically defined inthe appended claims.

A. panying drawings, in which:

Our invention '1sv illustrated in the afccom- Y `215 ,-1 Figure l is a sideelevation of the invention. Fig. '2l is anenlarged topV plan'view Tofa part of theinvention, and Fig. "3is a detail-'perspective view showing the means .for holding the sawin different adjusted positions.V i

Reference now/being had to the deans of the drawings byl numer s, 1 designates a sled,gshown asmounted/ pon the surface of l ice'land having `handles 2 securedlto the B25-opposite"- sidesthereof, and 3 designates beams pivotally mounted upon .the shaft 4, .and the forward ends' of said beams have journaled therein a shaft to which a saw 7 is .ixed and-alsoa sprocket wheel 8 about which vi740-asprocketchain 9' vasses and .also about la sprocket wheel 10 w ich is fixed to the dmving' wheel-mounted upon the shaft 4 in the ibase 12 ofthe engine. 11 designates a fender positioned-.at anylocation ad]acent to Said beams in contact with the u perfedges `ofthe han fdles 2, will ser'veto` limit the throw of said `5 0 beams incne direction and which willy hold the saw at its highest limit and theposi- 'tionshownin solid lines in Fig. 1. Across- Ypiece18" is secured'tothe handles and to j which bracket members 12%, shown in dotted lines-in'Fig. 2 oithedrawings, are fastened, and 12 designates a ratchet bar pivotally .mounted `upon said bracket: .members Upon'reference to Fig. 3. of the'drawin-gs,

slot `Min one edge thereof ada ted to receive the ratchet bar 12. Aresihent bar 15 is fixed at one end to the bolt 19 u on the edge of the crosspiece 13 and has a handle'l atone end and is slotted at 17` Vfor the -recep' tion of the bolt 5 which passes throiighmthe'k 'two cross-pieces 4 and 13 and servesA as aenl means to guide the bar 15.- -Said bar 15 adapted to engage one or anotherlof the y teeth of theratchet bar 124 for the purpose of 'holding the saw in dierent positions.

. When the bar 15 is in-nornal positi,j it leandefwill benbted that/it will holdtheratcletr bar 12 inthe slot 14 securely-and 'anydown- 'ward movement of the ratchet bar Vwilll be* prevented by reason V of the boltl which passes through the slot 17.-.

yBy the provision of anicecuttingappa'- ratus embodying the-featuresfof our inven- I tion, 1t will be noted that-.a simple and ehi:-

cient mechanism is afforded whereby,l when Ythesaw is not in operation, it maybe held above the surface upon whichthe'sled restsand, when in operation, it may haV heldby means of the ratchetand'resilientY bar shown with the locking pin serving to hold the parts securely in their adjusted position. What we claim to be'new is f I 1. An ice cutting apparatus comprising a I sled' with'I handles thereon, pivotal :beams mounted thereon, a rotatable saw carried by the beams, an engine andconnections be ter, cross-pieces connecting said bea1ns, `a4 re'- silient slotted bar fixed at one end toon'ecf said cross-pieces, a ratchet 'bar ivoted to the handle of the slot and engage by said bar, a bolt connecting said crosspiece?` and pass-` ing through the slot of said ar and tending to hold the latter from swinging vertically.

2. An ice cutting apparatus comprising a mounted thereon, a rotatable saw carriedby fino sled with handles thereon, pivotal' beams the beams, an engine and connectionsbe-V tween the same and saw for driving the lat.'-

te r, cross-pieces connecting said beams, oneI 10o` -of 'said cross-pieces having a slot in the edge.

thereof, 4a ratchet' bar pivoted to the handles positioned in saidslot, a resilient bar fasi tened at one end to'the edge of the slotted" cross-piece and engaging the teeth ofnthef ratchet bar,fand means for preventing the free end'of the bar from swinging.

3. An ice cutting apparatus comprising 'a sled With handles thereon, pivotal beams mountedthereon, a rotatable saw carried by the beams, an engine and connections between the same and saw for driving the latter, cross-pieces connecting said beams, one of said cross-pieces having a slot in the edge thereof, a ratchet bar pivoted to the handles positioned in said slot, a slotted bar fastened 10 at voneenfl to the slottedcross-piece'and provided vvith a handle at its free end, a bolt I' passing through saidl cross-pieces 'and the Aslots of said bar.

4 In testimony whereof We affix our signatures 1n presence of two Witnesses.
